Description

  The present invention relates to a solar panel mounting unit that is fixed to a side roof and is provided with a solar panel.

  In recent years, solar panels have been actively installed on the roof from the viewpoint of effective use of resources and effective use of solar energy.

  As a method for installing such a solar panel, a solar panel mounting unit is first fixed on the roof, and the solar panel is often mounted on the unit. Such a solar panel mounting unit that is fixed first can be fixed relatively easily to a flat roof (land roof), but is difficult to fix to an inclined roof. In particular, on the side roof, in order to improve the design, a step is provided on the underside of each side roof plate, and it becomes difficult to fix the solar panel mounting unit due to this step. May be.

  For such a problem that it is difficult to fix to the side roof, a base material, an envelope plate laid on the upper surface of the base material and forming an outer peripheral surface on the upper surface of the base material, and the envelope A plurality of elongate pedestals arranged in parallel with each other above the surface; and a mounting bracket having a receiving portion for supporting the elongate pedestal fixed or locked to the outer surface. A plurality of panel-like structures such as solar panels arranged on the gantry, and a presser plate having a presser portion for locking an edge of the panel-like structure and held by the gantry. There is a characteristic enclosure (for example, see Patent Document 1).

  In this enclosure (panel-like structure and its mounting unit, etc.), a Z-shaped mounting bracket is fixed to the surrounding board (roof plate), and a frame or a panel-like structure is placed on the Z-shaped mounting bracket. It is a structure to which an object can be attached, and the panel-like structure can be fixed at a position higher than the step portion of the side roofing board. However, since the Z-shaped mounting bracket used for raising the height is fixed to the base material (base plate) from the top of the surrounding plate (roof plate) by a fastening device such as a screw ( (Paragraph number 0007), there is a problem that it is difficult to finish the rain of a part hit by a screw or the like.

  Moreover, in order to avoid the step part of a horizontal roofing board in this way, if a solar panel is attached in the position slightly floated from the roofing board, a clearance gap will be made between a solar panel and a roofing board. When wind blows into this gap, an upward blowing load acts on the solar panel, which causes the solar panel mounting unit to be lifted off the roof panel and damaged, causing the solar panel to fall off. May happen.

  In order to solve such a problem of the blast load, a heavy object is attached to the roof of the building via a support hardware, and the blast load calculated based on the weight and shape of the heavy object and the field of the roof of the building There is a heavy object mounting structure in which a screw diameter, a minimum number of screws, and a mounting position of the screws are set based on the base plate thickness to fix the support metal to the base plate (for example, Patent Document 2). reference.).

  In this heavy load mounting structure, the blowing load and the like are calculated in advance to determine the screw diameter, the number of screws, etc., and the support hardware (solar panel mounting unit) is fixed to the roof with these screws, so it can withstand the blowing load. So that the solar panel can be installed.

  However, since this heavy load mounting structure is also intended to be fixed using a large diameter screw or a large number of screws, it takes time to position and drive the screw. There is a problem that it is difficult to finish the rain.
